of up to 3,000m/min. The diodes beam through the measuring plane and project the measuring object as shadow image on the opposite sensors. Depending on the exposure (shadow), the photodiodes give a signal, and the signals of the diodes are compared in a differential amplifier. This method is insensitive to extraneous light and vertical movement of the cable, so reliable results are continuously achieved. The Lump Series 2000 offers serial

interfaces such as RS485 and RS232. Optionally, a Profibus-DP interface or industrial field busses such as EtherNet/ IP-, DeviceNet or CANbus for direct connection to a PC or the display and control device Remote 2000 are available.

THE smallest lumps on the surface of hoses and tubes reduce their quality and often lead to a rejection of the complete production batch. Lump detectors, such as Sikora’s Lump Series 2000, are used during the production of hoses and tubes, for detecting online surface defects to assure quality. The Lump Series 2000 includes 2- and 3-axis measuring systems for product diameters from 0.25 to 35mm. The gauge heads detect at any speed lumps and neckdowns from 0.5mm length and 0.01mm diameter deviation. The devices distinguish between lumps and neckdowns, and report faults if the defined tolerance limits are exceeded. By the use of a powerful signal processor the number, height or depth and length of the fault location are evaluated, digitally displayed and stored. A highlight of the devices is the double sensor technology. With the help of light sources in combination with light sensors, they detect defects even under difficult conditions such as dirt or vibrations of the product. With the double sensor technology it is possible to reliably detect surface faults at a production line speed ACOUSTICEYE, a pioneer in non- invasive tube inspection for the global heat exchanger market, has announced the introduction of new capabilities for ultra-fast inspection of tubes up to 4" inner diameter in any shape or material. Achieving speeds as fast as 10 seconds per tube, AcousticEye’s Dolphin G3™ features patented acoustic pulse reflectometry (APR) technology, enabling accurate and reliable non-invasive inspection of even the most challenging tube sizes and configurations. An advanced yet easy-to-use tool, Dolphin G3 overcomes the limitations of many conventional inspection techniques. With

its simple operation, automated analysis and report generation, there is far less dependency on operator expertise. Commenting on the announcement, Yoav Harel, CEO of AcousticEye, said, “With the breakthrough performance of our new large diameter solution, it is now possible for the first time to inspect boilers, fin fans and other heat exchangers with the speed and accuracy needed to significantly increase operational efficiency and cost savings.” In successful field tests at several industrial sites, Dolphin G3 was able to identify defects not found by traditional inspection methods, such as holes, blockages, erosion and pitting, in a variety

of hard-to-inspect tubes including u-bends, boiler units and heat exchanger types with difficult access points. In some cases, tubes that were previously impossible to inspect were possible using AcousticEye’s non-invasive APR solution. The inspection results provided customers with component critical information for proper assessment of tube condition at a fraction of typical inspection cycle times and without the need for extra inventory of probes and standards.
